Tac2-N is associated with tumor metastasis of lung cancer patients. a The protein expression of Tac2-N was observed by IHC staining in lung cancer tissues. High Tac2-N expression group contains the ≥8 score patients. Low Tac2-N expression group contains the <8 score patients. Scale bars represent 50 μm. b Survival analysis of Tac2-N expression in I stage lung cancer patients by multivariate Cox regression analysis. c Survival analysis of Tac2-N expression in II stage lung cancer patients by multivariate Cox regression analysis. d Survival analysis of Tac2-N expression in III + IV stage lung cancer patients by multivariate Cox regression analysis. e The expression of Tac2-N was obviously higher in lung cancer patients with lymph node metastasis (N1–3) than that without lymph node metastasis (N0). ***P < 0.001. f The expression of Tac2-N was upregulated in lung cancer patients with metastasis than that without metastasis
